Why does the steering wheel suddenly become lighter with no resistance feeling?
2 Answers
Steering wheel suddenly becoming lighter with no resistance feeling is related to the power steering system. The specific explanations are as follows: 1. Hydraulic power steering: It is normal for the steering wheel to suddenly become lighter and lose feeling during acceleration. 2. Electric power steering and electro-hydraulic power steering: If the steering wheel suddenly becomes lighter and loses feeling, it indicates a malfunction. Relevant information about the steering wheel is as follows: 1. Definition: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. 2. Function of the steering wheel: It converts the force applied by the driver to the edge of the steering wheel into torque and transmits it to the steering shaft. It mainly consists of a skeleton, foam, and corresponding installation clips or screw holes for the driver's airbag (DAB).
I've experienced the steering wheel suddenly feeling light and lacking resistance several times. The most common cause is a sudden change in tire pressure - if one tire is severely underinflated or overinflated, the steering will feel unusually light. It could also be an issue with the steering system itself, like when the electric power steering system malfunctions; sometimes a minor sensor glitch can inexplicably increase power assistance. By the way, just the other day I encountered worn-out or loose tie rod end joints, which made the steering wheel feel as light as a toy car's. For safety, it's best to slow down and pull over immediately. If you're taking it to a repair shop, remember to clearly describe the exact moment when the steering became light - this is particularly helpful for troubleshooting.
